Worlds on Fire takes the reader on a fascinating tour of the mightiest volcanoes in the Solar System. From Kilauea volcano in Hawaii and Mount Etna in Sicily, it leaps to the lava fields and rilles of the Moon, retraces the historic footsteps of the Apollo astronauts and describes new volcanic provinces to explore. The three largest volcanoes of Mars - Olympus Mons, Alba Patera and Arsia Mons - are profiled, amongst others. The strange world of Venus, revealed by radar, opens our perspective of volcanism to features never seen before: pancake domes of puffed-up lava, and gigantic fault rings sitting over buried magma chambers. The tour of the Solar System ends with the only current eruptions outside Earth: the spectacular volcanoes of Io - Jupiter's fiery moon. This highly readable book, illustrated with the most recent imagery from spacecraft, will appeal to general readers, and students of Earth and planetary sciences.
